New Inspection Tool - Corrosion Under Insulation
In May 1995, Omega International Technology, Inc., began testing a new system to measure pip wall thickness using digital radiography (RT) scanning. This new system has the potential for being faster, less labor intensive, and shown improved accuracy over traditional ultrasound testing, and at a lower cost. Perhaphs best of all, scanning can be performed while the pipe is in service, insulation in place.
Digital radiography refers to the process of producing and analyzing X-Ray images using electronic devices instead of traditional film. For twenty years difital radiography, in the form of Computed Tomography (CT) scanners have been used to peer inside the human body. In the past decade, digital readiography has been used to inspect critical components for military and industrial applications. Even more recently, systems employing digital radiography are being used on processing lines in the food industry as an integral part of their quality assurance programs.
